Fi 9 is a sectional plan view on the line IX- X, Fig. 1.

Fig. 10 is a view to an enlarged scale of the parts shown tothe right of Fig. 9. I ave shown my invention combined with the lipparatus shown in atentgranted to me a 7, 1918 and num red 1,265,478.

a in 'cates the 'side of the car and a2 the car door as a whole which slides uponthe track g. b, b and b2 are the movable strips my invention and as much of the side o a caras 1s. necessaryv to lllustrate y door with the adjacent operating mechashown in my patent referred to. c is an actuating bar for the strips o, b and o2.

al is a bell-crank lever pivotcd at d2 to the side of the oar near the door and havin its shorter arm. connected by a pivoted lin to the operating bar c. Z7 is a handle upon the bar al. lever al and adapted to engage` through a staple or securing eye dxed to the side a of the car. d5 is the hook upon the latch f Z3l which ,is adapted to be engaged through da is a latch pivoted to the e0 the securing eye d and then have the car seal attached to it to lock the lever in the position shown in Fig. 1.

e is an uprightbar pivoted in bearings e2, e2a adjacent and parallel to the righthand edge orf the door a2, as shown in Fig. 7o

1. v e3 and e6 are ferrules or sleeves upon the bar e secured in place by set screws. e7 and es are engaging hooks extending from the sleeves e3 and e.

j is a sliding door adapted to reciprocate in gro'oves'or tracks jl, j? upon the door a2 to open and close a portal through the door a2. 'jz i's a bell-crank lever lpivoted at js to the door 7'* is a vertical, downwardly-y exbending short arm of the bell-crank lever i2. js is a pawl pivoted at one end to the arm j* of the bellelcrank lever i2. j indicates a series of equally-spaced teeth adj acent to the line of travel of the lowery end of the lever arm j* extending parallel to the line of travel of said arm and fixed to the door a2. The pawl j is adapted to engage the teeth je 'an it may turn about the pivot 94 to one side or the other of said arm, as

indicated in dotted lines in Fig. 1. js is @0 avlug extending from the right-hand end of the door j and having an aperture in its outer end. The hook e8 is adapted to engage through the aperture inthe lug js to secure the door y'. in its closed position.

k is a door adapted to open and close a portal in the upper portion of the door a3 and to slide horizontally in grooves or tracks 7a2, k2. 7:3 is a lug similar to the lug is but extendingfrom the door c. The hook T100 -is adapted to engage in the aperture. in the outer end of the lug je' to secure the door k in its closed positio 613. is a lever arm fixed tothe rod e and adapted to be manipulated to rotate said rod whereby the hooks e7 and es may be engaged Lerares with. their respective lugs k3 and js or may be turned to disengage them from said lugs. bs is an engaging lugl on the movable strip b adapted to pass over the lever arm e and secure said arm from rotation in the position in which the. hooks e7 and e8 are engaged with their respective lugs.

g indicates the track or way upon which the door a2 engages by means of hangers e, e5 having the usual friction rollers. The track g is a metal trough,` the cross-section of which is shown most distinctly in Fig. 4. lts web extends over the upper edge of the door a2 and deflects any rain or other loose material so that it shall not enter a car between the upper edge of the door and the car body. g2 indicates apertures, a series of which are formed along the outer edge of the lower'wall of the track g. The hanger e4 engages by a grooved wheel h (Fig. 4) the upturned outer edge of the track g. rlhe hanger e4 is formed in a loop in its lower end having horizontal portions et and @4b. e is an eccentric cylinder fixed to the upper end of the rod e and engaging through apertures in the horizontal portions e, e4th 'of the loop of the hanger e". By this arrangement, when the rod e is turned to the position to engage doors j and lc, the eccentric e9 acts upon the hanger e4 to press the upper edge of the door lat its right-hand portion close against the side of the car bordering the door-way. The other edge of the upper portion of the door is forced into close engagement with the car by theouter [lange of the track g which converges inward, as shown in Fig. 7, so as to bring the left-hand edge of the door into close engagement with the car wall when the door is closed.

e1 is a cylindrical sleeve fixed at the lower end of the bar e and having an outwardly projecting lug e (Fig. 6) thereon. 612 is a lug or dog rotatably sleeved upon the rod e just below the sleeve e1 and so located that it may .engage a part f fixed to a strip b2 and extending upward therefrom. 612a and em are shoulders upon the lug 4612 interposed in the line of travel of the lug en so as to allow a considerable free movement of said lug beforeit'engages said shoulders. When the rod e is turned'to its engaging position the lug e has engaged the shoulder em rotat ling the lug or dog e12 until it engages the vertically-extending portion of the part f and has pressed the door a2 rmly against 'the side of the car, thus` making-a tight,

closed engagement.

o l'l he door may have any 51de or end clearl ance thdught desirable.` When the door'is fully released, the bottom of the door swings outward from the car and comes to rest against brackets' or parts f, f. These parts f are securely fastened to the sliding plate b2 and atall positions project above said sliding plate half an inch, and the lower edge or the bottom of the door catches against these brackets or parts f, f and holds the door from further outward movement.

This outward movement is useful at large grain elevators, as it permits the grain that is pressing against the inside of the door to slide at once into the elevator hopper.

'The operation of the above-described device isas follows:

When the car is loaded and the door closed, it may be desirable to take out a por` tion of the load which may be of grain or similar material. ln such case the lever arml e113 is loosened by withdrawing the lugs b3 therefrom; said lever arm is then turned, rotating the rod e to disengage the hooks e7, e8 from their respective lugs. 'lhe pawl js being in the position shown in Fig. l, the

- j through the pawl i5 to move the door j a short distance toward lits open position. The bell-crank'lever is then moved until the pawl js engages Ithe next of the teeth j and the operation is repeated until the door j is opened to the extent desired. When it is desired to close the door y' the pawl jf is turned over as indicated in dotted lines, and the same operation of the bell-crank lever jg now acts to forcibly close the door.

llf it is desired to enter the car for any reason, while partly loaded, the door 7c at the upper portion of the door a2 may be moved along the tracks or grooves k2, czyto open the portal. `When the doorsy' and khave been closed the bell-crank lever al is moved to the position shown in Fig. l, forcing the bar I) at the right of the door a2 upward to engage the lug b3 over the lever arm @13. ln this position the door a2 is firmly and tightly closed and the doorsj and c are closed and locked by the hooks e7 and es. rl`he latch als is now engaged with the .securing'eye d and the seal is adjusted, thus securing all three doors by a single seal.

rlhe way in which the right-hand edgenof the door 1,2 is .forced closed against the side of the car by the turning of the rod e by means of the handle e13 has been described above in connection with the detailed description of the parts. f

The shape of the track g in cross section is such as to carry the water/away from the car door and discharge it at some distance from the joint between the door1 and the car wall. Y
